Abstract
The utility model relates to a can effectively reduce roof structure of regional noise of pantograph belongs to railway vehicle's roof structure. The automobile body is outside to bond through glued membrane no. 1 and shock pad, the shock pad bonds with sound insulating material, this sound insulating material upper portion is passed through glued membrane no. 2 and is bonded with sound absorbent, sound absorbent passes through on upper portion glued membrane no. 3 and bonds with sound insulating material, the sound insulating material top bonds through acrylic acid ester structure glue layer and aluminium matter dustcoat, the strengthening rib is located between shock pad and the aluminium matter dustcoat, fixed aluminium pig and the outside fixed connection of automobile body under the roof, fixed aluminium pig and aluminium matter dustcoat below fixed connection on the roof, fastening screw is fixed aluminium pig fixed connection under fixing aluminium pig and roof on damping gasket is with the roof, the insulated paint layer covers at aluminium matter dustcoat and fastening screw outsidely. The advantage is novel structure, has solved present automobile body pantograph position and has fallen the requirement problem not up to standard of making an uproar, and the construction is simple, and the installation of being convenient for is high with automobile body collocation degree, the suitability height.
Description
Technical field
This utility model relates to the roof structure of trolley coach, especially relates to a kind of roof structure that can effectively reduce pantograph region noise.
Background technology
Pantograph is widely used in trolley coach industry, is that electrically-driven car obtains the electrical equipment of electric energy from contact net.Along with advancing by leaps and bounds of Chinese Railway cause, the lifting again and again of running velocity while, roof pantograph region creates great noise, the problem occurring in that the comfortableness affecting passenger, therefore, the noise reduction in pantograph region requires the most all to be paid much attention to by each trolley coach manufacturer.
The most unique solution is exactly interpolation packing material between pantograph region lower-lying metal car body and roof panels, and to reach the effect of noise reduction, but owing to being limited by inside roominess, noise reduction is the most inconspicuous.
Summary of the invention
This utility model provides a kind of roof structure that can effectively reduce pantograph region noise, to solve the problem that below pantograph region, in car, noise reduction is bad.
This utility model adopts the technical scheme that: car body is outside bonding with cushion by glued membrane one, cushion is bonding with sound insulating material, this sound insulating material top is bonding with sound-absorbing material by glued membrane two, sound-absorbing material top is bonding with sound insulating material by glued membrane three, acrylate structural adhesive water layer is passed through bonding with aluminum matter outer housing above sound insulating material, reinforcement is between cushion and aluminum matter outer housing, fix aluminium block under roof to be connected with car body external stability, fix aluminium block on roof to be connected with fixing below aluminum matter outer housing, fastening screw fixes the fixing connection of aluminium block through damping pad by fixing on roof under aluminium block and roof, insulating lacquer layer covers outside aluminum matter outer housing and fastening screw.
The utility model has the advantages that novel structure, solve the problem that current car body pantograph position noise reduction requirement is the most up to standard, this roof structure passes through sound-absorbing material and sound insulating material, air borne approach has intercepted the transmission of noise, pass through cushion, the transmission of mechanical vibration has been intercepted on solid is propagated, thus the pressure of packing material noise reduction in alleviating car, indirectly solve the problem of packing material insufficient space in car, construction is simple, it is easily installed, aesthetics is higher, high with car body collocation degree, the suitability is high, can be according to the actual noise reduction demand of client, formulate different-thickness and the noise reduction components of internal structure collocation flexibly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Car body 16 is outside bonding with cushion 14 by glued membrane 1, cushion is bonding with sound insulating material 13, this sound insulating material top is bonding with sound-absorbing material 11 by glued membrane 2 12, sound-absorbing material top is bonding with sound insulating material 9 by glued membrane 3 10, acrylate structural adhesive water layer 8 is passed through bonding with aluminum matter outer housing 6 above sound insulating material 9, reinforcement 7 is between cushion and aluminum matter outer housing, fix aluminium block 4 under roof to be connected with car body external stability, fix aluminium block 3 on roof to be connected with fixing below aluminum matter outer housing, fastening screw 1 fixes the fixing connection of aluminium block 4 through damping pad 2 by fixing on roof under aluminium block 3 and roof, insulating lacquer layer 5 covers outside aluminum matter outer housing 6 and fastening screw 1.
Analyzing from acoustic angle, aluminum matter outer housing, sound insulating material, sound-absorbing material, sound insulating material, cushion, can be referred to simply as " every inhaling shock insulation " structure, this kind of structure has the obstruct of optimum, reduces noise (air borne)；Intercept, weaken the effect of mechanical vibration (solid propagation)；Sound-absorbing material has certain compressibility, makes noise reduction components sufficiently to contact with car body, and will not be by jack-up.
